Actionbar background color changes on scale

I used this code to change actionbar color that is used with appcompat lib:

actionBar.setBackgroundDrawable(new ColorDrawable(R.color.teleblue));

but in use color changes and in different screen sizes color is different. I don't want to clean the original question with tricky ways. how can I fix it?

thank you

Solution

  • R.color.teleblue is a resource identifier not a #AARRGGBB color.

    Depending on what type actionBar is some of following options may or may not be available:

    actionBar.setBackgroundResource(R.color.teleblue); // if it's Toolbar

actionBar.setBackgroundDrawable( // if it's ActionBar
    new ColorDrawable(
        actionBar.getThemedContext().getResources().getColor(R.color.teleblue));

actionBar.setBackgroundDrawable( // if it's ActionBar
    ContextCompat.getDrawable(
        actionBar.getThemedContext(),
        R.color.teleblue));

actionBar.setBackgroundDrawable( // if it's Toolbar
    ContextCompat.getDrawable(
        actionBar.getContext(),
        R.color.teleblue));
